Question

Select the correct options about the solubility of the following species in $H_{2}O$ and $N{H}_3$(aq).
$AgF,AgCN,AgCl,Agl,Ca{F}_2,CaC{l}_2$ :

• A. $AgF$ and $CaC{l}_2$ are soluble in $H_{2}O$
• B. $AgCN$ and $AgCl$ are soluble in $N{H}_3$
• C. $AgI$ and $Ca{F}_2$ are soluble in $H_{2}O$ and $N{H}_3$ (aq) both
• D. None of these

Answer 1

Answer: (A), (B)

The correct options are
A $AgF$ and $CaC{l}_2$ are soluble in $H_{2}O$
B $AgCN$ and $AgCl$ are soluble in $N{H}_3$

A. $AgF$ and $CaC{l}_2$ are polar compounds. Hence, they are soluble in water which is a polar solvent. Thus, the option A is correct.

B. $AgCN$ and $AgCl$ form complexes with ammonia as ammonia is a very good ligand. Hence, $AgCN$ and $AgCl$ are soluble in ammonia. Thus, the option B is correct.

C. $Ca{F}_2$ and $AgI$ are insoluble in water. Thus, the option C is incorrect.
